Thanks for posting your query
severe bouts of dry cough
may be due to many reasons. Chronic cough
has several reasons like
1. upper airway cough syndrome
and allergic rhinitis
7. non-asthmatic allergic rhinitis
These causes are to be excluded one by one by proper examination and physical examination and history taking. Do a chest x-ray. If there is sputum production then send the sputum for AFB smear, Gram stain. Go for spirometry
testing. But these tests should be guided by physical examination finding.
Therefore do consult a good pulmonologist and go for the investigations under his guidance.
